用法筆記
Frequently used as a countable noun ('a polio immunization') when referring to a single vaccine dose or personal vaccination event. As an uncountable noun ('the spread of immunization') it describes the general medical practice or population-level protection rate. Distinguish sense 1 from the legal/figurative sense of 'immunity' (exemption from penalty), which is a different word (immunity, not immunization).
